A modified M231 is the same as an M231, except a hole is drilled/milled into the fuze body to allow for external initiation of the M55 detonator in its fully safe position. Instead of staking, the modified M231 shall be secured to the M75 Grenade in such a way that will prov
21、ide the equivalent retaining force but allows for easy removal of the modified M231 without damaging the grenade. The complete M75 Grenade shall be conditioned to -5OO k 5OF for 4 hours prior to the test. Within 3 minutes after removal from the conditioning chamber, the modified M231 shall be initia
22、ted by dropping an external firing pin (P/N 9345321 for configur- ation of firing pin tip). Minimum energy required to fire the M55 Detonator is 0.75 inch-ounce. After initiation of the detonator, the smoke container assembly shall be inspected for any evidence of cracks. The lot shall be rejected i
23、f any crack occurs as a result of the initiation of the detonator.“ PAGE 11 * 6.3: Delete “US Army Armament Research and Development Command, ATTN: DRDAR-QAF-I“ and substitute “Armament Research, Development and Engineering Center, US Army Armament, Munitions and Chemical Command, ATTN: SMCAR-QAF-I“
